<p>PURPOSE:To make a starting circuit inoperative to prevent burglary even when an automobile is robbed and a door is opened by providing an engine start detector, a door opening detecting switch, a code number input device, a coincidence output holding circuit, a selection circuit, an off control circuit of an engine circuit, and a delay reset circuit. CONSTITUTION:When a door is opened in an engine stopped state, a door opening and closing detecting switch 1 turns on, and a signal of the switch 1 operates a door opening and closing detecting circuit 2 for inputting the signal to a delay reset circuit 12. Accordingly, since the circuit 12 starts to turn off a coincidence output holding circuit 10, for example, after 10-30 seconds, when the engine is started a contact 18 turns off to immediately stop an engine. But, when the engine is restarted within 10-30 seconds even if the door is opened, the engine starts because a coincidence output is outputted from the circuit 10. When the switch 1 detects the opening of the door in the engine stopped state, a code number checking circuit 9 is reset to have the holding output of the circuit 10 cleared. Therefore, the engine is started but it cannot start after 10-30 seconds unless the code number is inputted again.</p> |
